The cube has area of base 256 mm2.

Calculate the edge length, volume and area of its surface.


a =  16 mm
V =  4096 mm3
S2 =  1536 mm2


S=256 mm2 S=a2=a a a=S=256=16=16  mm S = 256 \ mm^2 \ \\ S = a^2 = a \cdot \ a \ \\ a = \sqrt{ S } = \sqrt{ 256 } = 16 = 16 \ \text { mm }
V=S a=256 16=4096=4096 mm3V = S \cdot \ a = 256 \cdot \ 16 = 4096 = 4096 \ mm^3
S2=6 S=6 256=1536=1536 mm2S_{ 2 } = 6 \cdot \ S = 6 \cdot \ 256 = 1536 = 1536 \ mm^2
